Works on almost every surface just make the right nozzle selection. It doesn't make a lot of noise. Cleaned windows on second floor very good power. I use it to clean my car the patio,gutters,mold on bricks love this machine.
this is an awesome pressure washer, I had 2 other different pressure washers that have been scrapped because they failed, the sun joe is by far the best, I love this pressure washer
Cleaned my deck real well. I had a problem connecting the hose to the unit, not much tread on the unit. Otherwise I am pleased with the pressure washer.
